I have spent the last few weeks trying to get my recursive sine wave formula for period calculations to work, but try as I might I can only get it to do so under ideal theoretical conditions. Once any significant noise, trend or combination thereof is introduced the calculations explode and give meaningless results. In light of this, I am no longer going to continue this work.

When applied directly to a theoretical but noisy sine wave series with a trend I find that this autocorrelation method performs better than my current period measurement algo, but on detrended data it is not as good. Since it is trivial to detrend price data, for now I am going to stick with my current method.
